tool fetch - 2xx HTTP response codes

This was solved in the ROS 6.41rc37

What’s new in 6.41rc37 (2017-Oct-02 06:47):

*) fetch - accept all HTTP 2xx status codes;

Now we may run fetch each after another, if web server return 202 and other 2xx status codes:

 
/tool fetch url="http://httpstat.us/202" keep-result=no
/tool fetch url="http://httpstat.us/202" keep-result=no
/tool fetch url="http://httpstat.us/202" keep-result=no

Thank you Mikrotik team!
